If Speight does miss time, his replacement will likely be redshirt junior John O'Korn, who transferred to Michigan from Houston.

O'Korn has completed 13 of 18 passes for two touchdowns in limited action this season. He spent a season and a half as Houston's starting quarterback -- throwing for 3,117 yards and 28 touchdowns as a freshman before losing his job as a sophomore.

O'Korn lost the offseason quarterback competition to Speight, despite adding another dimension to the offense with his scrambling and ability to extend plays.
